我正在尝试使用可穿戴设备,已经创建了一些来自微应用程序(运行在可穿戴设备上)的通知(有一些限制),现在想知道如何创建一个待定意图以便打开手机上的主应用程序。
我不知道是否还有其他方法。
然而它可以起作用。
在您的wear模块中建立一个通知,启动 wear 中的广播。
广播(在 wear 上运行)使用 Message.API 向移动模块发送消息。
在移动模块上,存在一个 WearableListenerService
,会启动移动设备上的 MainActivity。
在您的Wear中构建通知:
// Notification
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
//.setContentTitle(mNotificationUtil.getTitle())
.setContentText("Text")
.setContentIntent(getPendingIntent(this));
// Get an instance of the NotificationManager service
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(this);
// Build the notification and issues it with notification manager.
notificationManager.notify(1, notificationBuilder.build());
}
private PendingIntent getPendingIntent(MainActivity mainActivity) {
final String INTENT_ACTION = "it.gmariotti.receiver.intent.action.TEST";
Intent intent = new Intent();
intent.setAction(INTENT_ACTION);
PendingIntent pendingIntent =
PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
return pendingIntent;
}
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<receiver android:name=".MyBroadcast">
<intent-filter>
<action android:name="it.gmariotti.receiver.intent.action.TEST"/>
</intent-filter>
</receiver>
public class MyBroadcast extends BroadcastReceiver implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
Node mNode; // the connected device to send the message to
GoogleApiClient mGoogleApiClient;
private static final String WEAR_PATH = "/hello-world-wear";
@Override
public void onReceive(Context context, Intent intent) {
//Connect the GoogleApiClient
mGoogleApiClient = new GoogleApiClient.Builder(context)
.addApi(Wearable.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
mGoogleApiClient.connect();
}
/**
* Send message to mobile handheld
*/
private void sendMessage() {
if (mNode != null && mGoogleApiClient!=null && mGoogleApiClient.isConnected()) {
Wearable.MessageApi.sendMessage(
mGoogleApiClient, mNode.getId(), WEAR_PATH, null).setResultCallback(
new ResultCallback<MessageApi.SendMessageResult>() {
@Override
public void onResult(MessageApi.SendMessageResult sendMessageResult) {
if (!sendMessageResult.getStatus().isSuccess()) {
Log.e("TAG", "Failed to send message with status code: "
+ sendMessageResult.getStatus().getStatusCode());
}
}
}
);
}else{
//Improve your code
}
}
/*
* Resolve the node = the connected device to send the message to
*/
private void resolveNode() {
Wearable.NodeApi.getConnectedNodes(mGoogleApiClient).setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>() {
@Override
public void onResult(NodeApi.GetConnectedNodesResult nodes) {
for (Node node : nodes.getNodes()) {
mNode = node;
}
sendMessage();
}
});
}
@Override
public void onConnected(Bundle bundle) {
resolveNode();
}
@Override
public void onConnectionSuspended(int i) {
//Improve your code
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
//Improve your code
}
}
这段代码将会发送一条信息到你的手机,需要在你的wear/build.gradle文件中进行配置。
dependencies {
compile "com.google.android.support:wearable:1.0.+"
compile 'com.google.android.gms:play-services-wearable:+'
}
WearableListenerService
。/**
* @author Gabriele Mariotti (gabri.mariotti@gmail.com)
*/
public class ListenerServiceFromWear extends WearableListenerService {
private static final String WEAR_PATH = "/hello-world-wear";
@Override
public void onMessageReceived(MessageEvent messageEvent) {
/*
* Receive the message from wear
*/
if (messageEvent.getPath().equals(WEAR_PATH)) {
Intent startIntent = new Intent(this, MainActivity.class);
startIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startIntent);
}
}
}
在你的Mobile/AndroidManifest.xml文件中,需要声明该服务。
<service android:name=".ListenerServiceFromWear">
<intent-filter>
<action android:name="com.google.android.gms.wearable.BIND_LISTENER" />
</intent-filter>
</service>
还有这个mobile/build.gradle依赖项:
dependencies {
wearApp project(':wear')
compile 'com.google.android.gms:play-services-wearable:+'
}
我刚测试过的解决方案是在安卓应用程序上添加一个消息监听器,然后从可穿戴设备发送我想要执行的详细信息即可。
public class WearMessagesAPI_Service
extends WearableListenerService {
private static final String OPEN_APP_PATH = "/OpenApp";
@Override
public void onMessageReceived(MessageEvent event) {
Log.w("WearMessagesAPI_Service", event.getPath());
String activityKey = new String(event.getData());
if(activityKey.equals(...)) {
Intent myAppIntent = ... create intent ...
startActivity(myAppIntent);
}
}
}
别忘了将其添加到你的清单文件(manifest)中:
<service android:name=".wearable.WearMessagesAPI_Service">
<intent-filter>
<action android:name="com.google.android.gms.wearable.BIND_LISTENER"/>
</intent-filter>
</service>
我相信这就是全部内容了。 让我知道进展如何 :)
